VYINDOVf-SASH CONSTRUCTION.

Application filed April 18, 1924. Serial No. 707,525.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a sectional view showing a member as a stile of a window sash embodying my invention, the contiguous part of the portion of the window frame or guide being also shown.

Figure 1 is a view similar to Fig. 1, the window frame being omitted.

Figure 2 is a fragmentary view of the stile.

Figure 3 is an isometric view of another form of sash embodying my invention.

This sash construction comprises generally a sheet metal member as a stile in the form of a channel, which is open at the edge of the sash, and also formed to receive the margin of the pane of glass of the window, and spring means arranged in the channel and tending to thrust the opposite side walls of the channel outwardly against the side walls of the groove or the channel of the window frame in which the sash slides.

1 designate the sheet metal member or stile in the form of a channel open at 2, at its free edge; this member 1, being of a metal as aluminum, having no or very little inherent resiliency. The member 1 is Ushaped in general form in cross section, and its side walls are usually integral with the bottom 3 of the channel.

The bottom 3 of the channel is also formed with an external groove 4 for receiving the margin of the glass pane of the window or holders or reinforcing strips for the margin of such pane.

5 designates the window frame or guide which is formed with a channehthe opposite walls 6, 7, of the member 1 slidably engaging the opposite walls of the channel or guide 5.

The spring means for holding or pressing the walls 6, 7 against the inner channel walls toms of the recesses 12 and the inner face of said wall 7, so that, the springs tend to press the wall 7 outwardly away from the block 9 and also thrust the wall 6 in the opposite direction.

Usually the edge of the block 9 terminates near or beyond the outer edge of the walls 6, 7, in order to be trimmed down to fit the sash to the window frame. I

In Figure 3 the spring means is shown as a member 13 in the form of a channel seated into the channel of the member 1, between the side walls 6, 7, and resting on the bottom wall 10 of the groove 4;, the channel member 13 being of a resilient metal and being tensioned to thrust the walls 6, 7 outwardly away from each other, and hence, outwardly against the walls of the guide channel 5.

By reason of this construction a metal sash can be used, constructed of light metal, as aluminum, and the sash tensioned to fit the window guides or stops, without the use of weather strips and tightening devices.

The window construction is particularly advantageous for railway cars and other vehicles, and is more particularly adaptable on account of its economy of manufacture for use in motor busses, where cheap but eiiicient weather tight windows are a necessity.

What I claim is: a 1

1-. A window sash construction comprising a sheet metal member in the form of a channel, a block arranged in the channel and thrusting at one side against one of the side walls of the channel, and springs interposed between the block and the other side wall of the channel.

2. A window sash construction comprising a sheet metal member, in the form of a channel, a filler block located in the channel and thrusting against one side wall of the channel, the block being formedwith recesses at intervals extending inwardly from its other side, and-springs located in the recesses and thrusting at their inner ends against the bottoms of the recesses, and at their other eniis against the other sidewall of the channe 3. A window sash construction comprising a sheet metal member, in the form of a channel, the bottom wall of the channel-shaped'to form an external groove to receive the pane 6f glflSSyfl block locatedin the channel and engaging the bottom wall of the groove, the block thrusting at one side against one of the sidewalls of the channel, and springs set into the block and arran ed to thrust against the other side wall of the channel.

4. A window sash construction comprising a sheet metal member in the form of a channel, a block arranged in the channel and formed'with openings at intervals and'compression springs extending into the openings and acting to thrust apart the side walls of the channel,

In testimony whereof, I have hereunto signed-my name,iat Syracuse, in the county of Onondaga, and in the State of New York, this 22 day of March, 192

EDWARD F. CHAFFEE.
